But that's a global setting for all qemu domains.  I can see where it
might make sense to compression for some domains but not others, at
which point exposing the ability to suggest a non-default compression
makes sense.

On the other hand, if we agree that a qemu.conf setting is adequate,
then this patch still needs a respin, in order to honor the conf-file
default rather than hard-coding it to raw.

So either way, we need more discussion and probably a respin.
